What was the extent of Palestine in Biblical times?

Palestine was not the name used in Biblical times. In the Old Testament, the area is the Land of Canaan, later to become Eretz Yisrael, the Land of Israel. A precise description is given in Numbers, Chapter 34:

And the Lord spake unto Moses, saying, Command the children of Israel, and say unto them, When ye come into the land of Canaan; (this is the land that shall fall unto you for an inheritance, even the land of Canaan with the coasts thereof:)
